| 1 | Improving Yield and Nitrogen Use Efficiency Simultaneously for Maize and Wheat in China: A Review显示文摘同时完成两高收益和高氮使用效率(NUE ) 与对食物,自然资源的弄空,和环境的恶化的增加的全球需求成为了主要挑战。作为在世界上的 N 化肥的最伟大的消费者,中国农民滥用了 N,并且因为 N 举起收益关系的有限理解,在庄稼 N 需求和 N 供应之间有差的 synchrony。处理这个问题,这研究为二个学生的不同收益范围评估了全部、动态的 N 要求庄稼(玉米和小麦) ,和到 N 管理策略的建议改进。整个植物的 N 未葬举起要求每谷物产量(N req ) 开始与谷物收益改进死亡了然后停滞,并且然而,大多数农民仍然相信更多的化肥和更高的谷物产量是同义的。当玉米产量增加了从时 < 7.5 到 > 12.0 Mg 哈 −1, N req 从 19.8 ~ 17.0 kg Mg −1 谷物减少了。为小麦,它为谷物产量从 27.1 kg Mg −1 谷物减少了 < 4.5 Mg 哈 −1 到为产量的 22.7 kg Mg −1 谷物 > 9.0 Mg 哈 −1 。同时,干燥物质的百分比和在中间迟了的成长季节的 N 累积与谷物产量显著地增加了,它显示 N 授精应该在中间迟了的阶段被集中当农民们经常在播种前或在早生长阶段期间使用了 N 化肥的多数时,匹配庄稼需求。我们因此开发了同时增加谷物产量和 NUE 的综合土壤庄稼系统管理策略。 | MENG Qingfeng YUE Shanchao HOU Peng CUI Zhenling CHEN Xinping | 2016 | Pedosphere2016，26，2： | 51 |
| 2 | Elucidating Variations in Nitrogen Requirement According to Yield, Variety and Cropping System for Chinese Rice Production显示文摘Better understanding of the factors that influence crop nitrogen(N) requirement plays an important role in improving regional N recommendations for rice(Oryza sativa L.) production. We collected data from 1 280 plot-level measurements in different reaches of the Yangtze River, China to determine which factors contributed to variability in N requirement in rice. Yield, variety, and cropping system were significantly related to N requirement. The N requirement remained consistent at about 18.6 kg N Mg^(-1)grain as grain yield increased from 7 to 9 Mg ha^(-1), then decreased to 18.1, 16.9, and 15.9 kg N Mg^(-1)grain as yield increased to 9–10, 10–11, and > 11 Mg ha^(-1), respectively. The decreased requirement for N with increasing yield was attributable to declining N concentrations in grain and straw and increased harvest index. Super rice variety had lower N requirement(17.7 kg N Mg^(-1)grain) than ordinary inbred and hybrid varieties(18.5 and 18.3 kg N Mg^(-1)grain, respectively), which was a result of lower grain and straw N concentrations of super rice. The N requirements were 19.2, 17.8, and 17.5 kg N Mg^(-1)grain for early, middle, and late rice cropping systems, respectively. In conclusion, the rice N requirement was affected by multiple factors, including yield, variety, and cropping system, all of which should be considered when planning for optimal N management. | ZHANG Yi CHEN Xinping MA Wenqi CUI Zhenling | 2017 | Pedosphere2017，27，2： | 7 |
| 3 | Umbilical cord mesenchymal stem cell transplantation for the treatment of Duchenne muscular dystrophy显示文摘Due to their relative abundance,stable biological properties and excellent reproductive activity,umbilical cord mesenchymal stem cells have previously been utilized for the treatment of Duchenne muscular dystrophy,which is a muscular atrophy disease.Three patients who were clinically and pathologically diagnosed with Duchenne muscular dystrophy were transplanted with umbilical cord mesenchymal stem cells by intravenous infusion,in combination with multi-point intramuscular injection.They were followed up for 12 months after cell transplantation.Results showed that clinical symptoms significantly improved,daily living activity and muscle strength were enhanced,the sero-enzyme,electromyogram,and MRI scans showed improvement,and dystrophin was expressed in the muscle cell membrane.Hematoxylin-eosin staining of a muscle biopsy revealed that muscle fibers were well arranged,fibrous degeneration was alleviated,and fat infiltration was improved.These pieces of evidence suggest that umbilical cord mesenchymal stem cell transplantation can be considered as a new regimen for Duchenne muscular dystrophy. | Xiaofeng Yang Yifeng Xu Naiwu Lu Yibin Zhang Hongmei Wang Xin Lu Jiping Cui JinxuZhou Hong Shan Yanxiang Wu Xinping Liu | 2011 | Neural Regeneration Research2011，6，10： | 4 |
| 4 | Can we reestablish a self-sustaining population?A case study on reintroduced Crested Ibis with population viability analysis显示文摘Background:One of the most challenging tasks in wildlife conservation and management is clarifying which and how external and intrinsic factors influence wildlife demography and long-term viability.The wild population of the Crested Ibis(Nipponia nippon)has recovered to approximately 4400,and several reintroduction programs have been carried out in China,Japan and Korea.Population viability analysis on this endangered species has been limited to the wild population,showing that the long-term population growth is restricted by the carrying capacity and inbreeding.However,gaps in knowledge of the viability of the reintroduced population and its drivers in the release environment impede the identification of the most effective population-level priorities for aiding in species recovery.Methods:The field monitoring data were collected from a reintroduced Crested Ibis population in Ningshan,China from 2007 to 2018.An individual-based VORTEX model(Version 10.3.5.0)was used to predict the future viability of the reintroduced population by incorporating adaptive patterns of ibis movement in relation to catastrophe frequency,mortality and sex ratio.Results:The reintroduced population in Ningshan County is unlikely to go extinct in the next 50 years.The popula-tion size was estimated to be 367,and the population genetic diversity was estimated to be 0.97.Sensitivity analysis showed that population size and extinction probability were dependent on the carrying capacity and sex ratio.The carrying capacity is the main factor accounting for the population size and genetic diversity,while the sex ratio is the primary factor responsible for the population growth trend.Conclusions:A viable population of the Crested Ibis can be established according to population viability analysis.Based on our results,conservation management should prioritize a balanced sex ratio,high-quality habitat and low mortality. | Yashuai Zhan Fang Wang Zhenxia Cui Min Li Xia Li Xinping Ye Xiaoping Yu | 2021 | Avian Research2021，12，2： | 2 |
| 5 | Seawater hydraulics:From the sea surface to depths of 11000 meters显示文摘Using seawater as the working medium,the seawater hydraulic system has significant advantages in the deep sea,such as eliminating contamination caused by oil leaks,no oil tanks,and the ability to automatically adapt to sea depths.As working depths increase,seawater hydraulic technology faces enormous challenges.First,the physical and chemical properties of seawater,such as density,temperature,and composition,change significantly.Second,hydraulic components are subject to an environmental pressure of up to 110 MPa,which causes serious deformation or even seizure of moving pairs and significantly affects the efficiency of hydraulic components.The friction and wear characteristics between the moving pairs also significantly change with the change in sea depth,therefore developing the matching material according to depth is necessary.Finally,the cavitation characteristic of a valve port is obviously different from that on land,so special material and structure should be used to improve the service life of the valve port.These factors severely restrict the improvement of the working depths and characteristics of seawater hydraulic components.This article focuses on the abovementioned problems and provides solutions for deep-sea seawater hydraulic technology. | LIU YinShui CHENG Qian WANG ZhenYao PANG Hao DENG YiPan ZHOU XinPing LUO XiaoHui CUI Yan WU DeFa | 2022 | Science China(Technological Sciences)2022，65，9： | 2 |

| 16 | A case study of digital-twin-modelling analysis on power-plant-performance optimizations显示文摘China Energy’s National Institute of Clean-and-Low-Carbon Energy(NICE)is developing a Power Plant Smart Management(PPSM)platform that employs digital-twin technology to undertake techno-economic modelling analysis on China Energy’s existing coal-fired power-plant units and explore cost-effective solutions to improve those plant units’thermal efficiencies and operating performance.This paper presents a case study of PPSM on a 320-MWe coal-fired thermal power-plant unit,demonstrating how the digital-twin technology was employed to explore and analyse optimization solutions.Various optimization solutions and their cost-effectiveness were assessed using the digital-twin-modelling analysis;the results indicated the optimization solutions are expected to improve the plant unit’s operating efficiency and reduce its current electricity-generation coal consumption by up to 3.5 g/kWh standard coal equivalent(sce),worth annual fuel-cost savings of approximately 4 million RMB for a single unit or 8 million RMB for the two identical 320-MWe units that the power plant currently operates.The digital twin was also employed to assess the power-plant unit’s operating economics during both summer and winter.In summer,when the unit operates in electricity-generation-only mode,the unit’s operating thermal efficiency could drop by up to 6%points following the grid demand of load changes from 100%maximum continuous rating(MCR)down to 30% MCR,resulting in an~45 RMB/MWh increase of electricity-generation cost.In winter,when the unit operates in combined heat and power(CHP)cogeneration mode,for the same boiler load,the CHP operation increases the plant unit’s operating profit with increasing district-heating duty,although the relative profit gain from the CHP cogeneration could start to decrease when the district-heating steam-extraction flow increases to a certain point that varies depending on the market prices of heat and electricity,while the fuel cost was found to be equivalent to~50% of the unit’s total CHP income cogenerated from its electricity and district heat outputs. | Bin Xu June Wang Xinping Wang Zhihong Liang Liming Cui Xiao Liu Anthony Y.Ku | 2019 | Clean Energy2019，3，3： | 1 |
